As the school holidays were coming to an end, we decided to take the kids to Kew Gardens. It turned out to be a lovely day out, we spent five hours trekking around exhausting them and still managed to see only half of the attractions (I was so disappointed to miss the tree-top walk). It turned out to be one of the most child-friendly places I have been to, with free entry for children, plenty of space to run around and separate play places for children (my favourite was the sand pit full of lentils - what a great idea). They even had free wheelchairs for when mum-in-law got too tired to walk, which the kids had great fun carting each other around in.
One of the things that appealed to me about the Japanese Gardens was the beautiful sense of and order - appealed to my inner neat freak.
